Expedia/Trip Advisor EV Charging amenities-filter option

Electric Vehicle car owners are pioneers that want to change the word; therefore, we face some difficulties such as planning a trip. We need to go to different websites and app to make sure we have Supercharging or Charging Point on the hotel or nearby. When searching for hotels we have no option to filter hotel that has Electric Vehicle (EV) Charger; so, we are asking for Expedia and Trip Advisor to add the option/filter so they could win more clients and/or make their current clients happier. It could be just availability option or even better filter by Charging Level. For Expedia and Trip Advisor would be easy to do because they could just shoot an email asking all hotels to answer if they have EV Charger. If positive, ask how many and what level the chargers are.
